In Odoo ce v14, when creating invoice from a purchase order I got the following error:

_prepare_account_move_line() missing 1 required positional argument: 'move'" while evaluating
'if records:\n                action = records.action_create_invoice()'

Creating invoice from sale order works fine, this issue appear only for purchase orders.

I am a newbie in Odoo I can't get out of this.

Help will be appreciated.

Thank you.
